S TEP FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 297,991, dated May 6, 1884. Application'filed February 25, 1884. (No model.)

To aZZ whom, it may concern..-

Be it known that I, GEORGE F. HARWOOD, of Worcester, in the county of Worcester and State of Massachusetts, have invented new and useful Improvements in Adjustable Steps for Bicycles and other Velocipedes, of which thefollowing is a specification.

In the accompanying drawings, in; which similar letters of reference indicate like parts, Figure l is a perspective view of an adjustable step embodying my invention secured to the perch or backbone of a bicycle. Fig. 2 is a plan view of the same, showing the perch in horizontal section. Fig. 3 is an elevation of the same in position for use. Fig. 4 is a transverse vertical section on line a: y, Fig. 3. Fig. 5 is a view'of-an adjustable step, with its parts separated.

The step proper consists of a frame or loop of metal, A, provided'with teeth a, preferably extending upwardly, and inclined toward the back of the step, and with the guard or flange A (substantially as described in the Letters Patent of the United States granted to me June 13, 1882) and the back plate,' A, curved to fit the perch K, and provided with a central vertical slot, B, extending from the upper edge of the back or surface of the step downward almost but not quite to the lower extremity-of the said back, and connecting with the central opening, 0, in the horizontal portion of the step. A bolt, D, passes through the horizontal opening E, Fig. 5, and is held in place by a suitable nut, cl.

H is a spring-band, of thin metal, provided with elongated openings h, through which the bolt D passes. This spring-clamp tightly embraces the perch .K, and its ends lie under the nut 01 and the head of the bolt D. It will readily be seen that this step requires no other attachment to secure it to the perch, may be applied to the latter at any height, and is perfectly adj ustable. By tightening the nut d on the bolt D, the ends of the spring-band H are drawn against the opposite sides of the step, and by still further tightening said nutthe two sections of the back plate, A, formed by the slot B, are forced slightly toward each other, thus crowding the back plate and spring band firmly against the perch K. It will be seen that in this device the entire circumference of the perch is in actual contact with either the back plate or the spring-band, thus producing a complete frictional ring, so that it isimpossible for the step or band to be moved either horizontally or vertically, except by loosening the nut d Owing to the bolt D being placed so high in the step, the weight of the rider when mounting has a tendency to make the lower end of the back plate bite the perch, so that when the step is in actual use it is even more secure in-its position than when no weight is placed upon it. Y By means of the elongated openings h in the spring-band H, this band is adapted to be applied to bicycle-perches of different, diameters. Different sizes of bands may be used, and the adjustability of the step is enhanced by making the slot, which may extend the entire length of the back plate, (and be open at each end,) of sufficient breadth.

Having thus fully described my invention, what I claim, and desire to secure'by Letters Patent, is

1. In a stepfor. bicycles and other velocipedes, the combination, with the band H, bolt D, and nut d, of the step A, the back plate, 'A, thereof being provided with the slot B, extending from a point near the lower end of said back plate to the surface of the step, sub- GEORGE F. HARWOOD.
